Abstract
In a method for transmitting data in a control system, a first station generates a data frame having a plurality of data fields. At least one data field to be filled with transmission data is clearly assigned to each further station. The data frame is transmitted as an outgoing data frame from one station to the next, with every further station filling the respectively assigned data field with transmission data. The last station returns the data frame as a returning data frame to the series of stations. The stations read extraneous transmission data from the data fields in the returning data frame. Preferably, the respective data fields are individually assigned to the stations.
